Figure caption: Left panel: map of angle differences, Δθ, between the POL-2 observations, θ obs, and the best-fit WK model, θ model. Positive and negative values mean that magnetic field orientations of POL-2 observations are directed counterclockwise and clockwise from those of the best-fit WK model, respectively. The pixels outlined in green are excluded from our analysis due to high uncertainty, as their radii of curvature are smaller than the size of the box used in our analysis, 36″ × 36″ (see the Appendix B for details). Right panel: histograms of the angle differences. The orange histogram includes all pixels in the left panel. The green histogram excludes the pixels outlined with green in the left panel. The dashed line shows the Gaussian fitted to the green histogram, the standard deviation of which is 19°.
